Algorithmic Information Bounds for Distances and Orthogonal Projections
Peter Cholak, Marianna Csörnyei, Neil Lutz +3
We introduce a new technique for proving bounds on the Kolmogorov complexity of geometric objects in Euclidean space, such as points and lines. We apply this technique to prove two…
Fractal dimensions and profinite groups
Elvira Mayordomo, Andre Nies
Let be a finitely branching rooted tree such that any node has at least two successors. The path space is an ultrametric space: for distinct paths let $d(f,g)= 1/|T…
Bounding the dimension of exceptional sets for orthogonal projections
Peter Cholak, Marianna Csornyei, Neil Lutz +3
It is well known that if is an analytic set of Hausdorff dimension , then for a.e.\ , where denotes…
Normality, Relativization, and Randomness
Wesley Calvert, Emma Grunner, Elvira Mayordomo +2
Normal numbers were introduced by Borel and later proven to be a weak notion of algorithmic randomness. We introduce here a natural relativization of normality based on generalized…
